Growth curves of seven strains of lactic acid bacteria isolated from Kimchi were graphed, when they were cultivated at 3$0^{circ}C$ in filter sterilized Chinese cabbage juice containing 0, 2, 4 and 6% salt, and then lag time and generation time were calculated. The shapes of growth curves were changed differently among strains, as salt concentrations were increased. The addition of 2~4% salt resulted in prolongation of lag time were most omspicuous in Leu. Paramesenteroides and Leu. Mesenteroides subsp. Dextranicum, and the next in Leu. Mesenteroides subsp. Mesenteroides,m Lac. Bavaricus and Lac. Gomohiochii, and the least in Lac. Plantarum and Lac. Brevis. And then the prolongations of generation time were most remarkable in Lac. bavaricus and Lac. Homohiochii, and the next in Leu. Mesenteroides subsp. Mesenteroides, Leu. Mesenteroides subsp. Dextranicum and Leu. Paramesenteroides, and the least in Lac. Plantarum and Lac. brevis. By increasing salt concentrations from 0 to 2%, the generation times of Leu. Cesenteroides subsp. Dextranicum and Leu. Mesenteriodes subsp. Mesenteroides were prolonged slightly, while those of Lac. Homohiochii and Lac. Brevis were not changed, and those of Lac. Plantarum, Lac. Bavaricus and Leu. Paramesenteroides were shortened slightly. As salt concentrations were increased from 2% to 4%, inversions in the order of generation time occurred among strains. As a whole, lower salt concentrations were more favorable for the growth of Leuconostoc strains, while higher salt concentrations were for Lactobacillus strains.
